Just got the rest of the parts for my last quad GPU rig. Got the X2 7750 pumping the blood in this one. Using 2x 8800GTS G80 and 2x 9600GSO and hopefully they will play nice together. If anyone is planning on the 8800GTS G80 for folding, don't. They are power hogs due to the 90nm process and produce twice the heat of the 9600GSO's. I should have picked up different cards, but they are here and paid for. This will be my most power hungry rig to date. I'll let you know the wattage later tonite.
